Tlhisinventioh relates toa windowi'rame, 7

adapted to hold and guide vertical sashes and a vertical window screen, which isinovable in close proximity to the upper sash, the frame including outside and inside vertical casing members and an intermediate vertical pulley stile, joined to and connectingsaid members, the stile and the outside and inside members forming a vertical well in which the usual sash eights, supported by co'rd's trained over pulleys on the pulley stile, are movable. i

The inner edge portion of the outside member projects across the sash-guiding inner face of the stile, and cooperates there with in guiding the upper sash. In screened windows the inner edge of the outside member is provided with a longitudinal vertical tongue, adapted to enter a groove in a screen frame and guide the screen in its vertical movements.

I-Ieretofore the tongue or screen guide has been a strip formed separately from the outside member and attached to the inner edge thereof by small nails or brads.

Among the objections to a separately formed screen-guide strip are the following The strip is necessarily narrow, and when made of wood, as is usually the case, is liable to be split by the attaching nails, and. the nails are liable to be crippled in driving, so that they form projections liable toscatch the surface of the groove in the screen frame and impede the movements of the screen, The workman is liable to improperly locate the strip in nailing it to the outside member, so it may be either too near the path of the upper sash and cause binding of the screen frame thereon, or too far from said path and form a crevice through which insects may enter. A careless workman may cut the strip too short, so that a space through which insects may enter is formed at one or both ends of the strip.

The object of my invention is to obviate the above-mentioned and other objections, and provide a screen guide which is integral with the outside casing member, has a pre determined location on the projecting inner edge thereof, so that there is no liability of an improper location of the guide, and is coextensive with the member, so that an insect-admitting space cannot be formed at an end of the ide by carelessness ot a workman, the guide being free from metallic fastenings, so that there is no liability of thereon,

splitting the guide and creating projections attain this object by forming longitudinal rabbets in the inner edge of the outside casing member during the operation of making said member, and before it incorpo rated into the frame, the form of the rabbets beingsucli that the outside member lSPl'O", vided onits inner edge with a longitudinal tongue constituting a screen guide integral and coextensive in length with said member andhaving a predetermined location there on. i a

Of the accompanying drawings forming a part of this speeification,

Figure l shows in perspective a portion of a window irame, the outside casing member of which is provided with an. integral screen guide in accordance with my invention.

Figure 2 is a fragmentary horizontal section, showing a portion of theoutsidc casing member, having the integral screen guide, a portion otthe pulley stile, a portion ofan upper sash, and a portion of a screen frame engaged with the guide. j,

Figure 3 is a -tragmentary section, showing by full lines portion of the blankfronr which the outside casing member, shown by Figure l, is made, and by brokenlines, the

form and location of the rabbets which form v the screen guide. p

Figure 4 is a fragmentaryse'ctional view, showingaportion of the outside casing member at the opposite side of the frame from the member shown by Figures 1, 2 and 3, and another portion of the screen frame.

The same reference characters indicate the same parts in all of the figures.

Figure 1 shows a portion of one of the upright sidesof a window casing, the 0pposite side being similarly constructed.

12 designates the inside vertical casing member, 13 the outside vertical casing memher, and 14: the pulley stile, the upper portion of which supports the pulleys on which are trained the sash cords supporting the usual sash weights movable in the vertical well formed by the members 12 anr l8 and the stile 14. The stile is joined to and connects the members 12 and 13, as usual. 15 designates a portion of the stool or sill member of the casing, joined as usual to the lower ends of the casing members and stile. The inner edge portion. of the outside men1- ber 13, projects across the sash-guiding inner face of the stile to cooperate with the stile and theusual parting bead 16 in guiding the upper sash 17; The lower sash (not shown) is guided by the stile, the parting bead and the inside stop bead 18, as usual.

In carrying out my invention, I cut in the inner edge. of the member 13, before the latter is incorporated in the casing, two

longitudinal grooves or rabbets 19, 19, at opposite sides of the longitudinal center of said edge. The form of said inner edge, before the rabbets are cut, is shown by full lines in Figure 3. The rabbets may be cut quickly and accurately by cutters of a wood-working machine, known as a straight molder, and

maybe formed by the same operation which forms, in the inner side of the member 13,

the usual groove 21 which receives the tongue 20 on the outer edge of the stile 14:. The form of the rabbeting cutters is such that they inwardly offset portions of the inner edge of the members'13, and form between said offset portions a longitudinal tongue 22, integral with the member and constituting a guide for a screen frame 23, having a groove 24:, receiving the guide. Said guide preferably has oppositely inclined sides merging into a rounded outer edge, as best'shown by Figure 2. v

It will now be seen that the member 13 is provided, at an inconsiderable expense, with a screen guide which is not open to the above-mentioned objections applying to a screen guide separately formed and nailed to said member, the integral guide being given an exactly predetermined location, and free from metallic fasteners.

It will also be seen that the cost of providing the screen guide 22 is much less than that of providing a guide by nailing a separately formed strip to the inner edge, which is usually about twenty cents for each win dow. The only expense involved in providing the integral guide is the slight increase in the original width of the member 13 required to permit the cutting of the rabbets 19. This amounts to about one cent for each member 13. The outer edge of the integral guide 22 may be considerably narrower than would be advisable in a separately formed and nailed on strip.

In accordance with the usual practice, the

guide-engaging groove 24: in one of the upright members of the screen is relatively shallow and closely fits the guide 22 at one said members, the inner edge portion of the outside member projecting beyond the sash guiding inner face of the stile, to cooperate therewith in guiding a sash, and having longitudinal rabbets formed therein at opposite sides of the longitudinal center of said edge, whereby said outside casing member is provided on its inner edge with an integral longitudinal tongue, constituting a screen guide, coextensive in length with the casing member and having a predetermined location thereon.

In testimony whereof I have aiiixed my signature.
